ALL WHoM 1T MAYfeoNonRN;

Be it knowuthat I, EDWINF. ANDREWS, ofGlasgow, in the county of Howard, and in the State of Missouri, invented certain new and useful Improvements in Brick-Machines and de'hereby declare that the follows a full, clear, and exact description thereof, referenceheing had to the accompanying drawings, and to thei rs of reference marked thereon, making a part of this specification. Figure 1 represents a. plan view with the vrollers taken off. Figure 2 represents a horizontal section. Figure 3 represents an end view. In the annexed drawings, A represents a rectangular frame or casing for the machine, which is supported .suitable feet, a a. Near the centre, and at one end of this frame, is a cross-shaft, B, upon which are :cd eccentric cams C C C. These cams are made in the form substantially as represented, and placedupon h'aft so that their striking-partis will operate at diierent times. Encircling each cam is a quadri'lpteral e, D DD', the frames D D being composed of two'vertical bars of wood, connected at the top and` bottom orizontal metal rods or shafts, as seen. The frame Dl beingintended to operate with its cam in a. diferent ier, as will be-more fully illustrated, is constructed so that its wooden bars are at the top 4and bottom, and netallic rods areY at its sides. Connected to the rear end of the frames D D, near their centres, are guides which have their bearings in the end of the frame A', and work in a horizontal manner, as their respective es are operated. The frame D has a similar guide, d', upon its top, which works vertically in its opening e frame. It will'beseen that one ofthe cams, C, has a semi-elliptical shaped ilan'ge on its face b, and that if the frames, D, is provided with an upper and lower projecting bar, E E', secured bymeans of set-screws v the metal rods, so that the surface of this flange strikes each of these hars alternately as it revolves. e bars and anges may be formed-on each cam and frame for assisting the operation thereof. Upon the )ortion of the frame A, at the end opposite the shaft B, are' two crossrolle'rs, F F, which are supposed to :heath a hopper, and are provided with suitable bearings, and provided with a cog or band-wheel, :v x', upon and. Beneath the inner peripheryof these rollers, in the body of the box A, is a throat, G, formed bythe `ltable walls gg, into whichthe clay falls after being crushed between the rollers F F.- Directly under this 'it is the upper plunger, H. This plunger is connected to the first frame, D, by means of a rod,f, and is orted upon a smallpartition, t, which separates the two plungers. v There are small ways ou th'e sides of 10X, and small grooves, e, on'the sides of the plunger, so that it readily slideis back and forth, and is kept I ace. The plunger has two or more suitable-shaped openings, L h', into Whichthe clay falls after passing :gh the throat G. Forward of this plunger H is a receptacle, V, left in th e box, and into which the clay rried andfalls through the recesses h h', as the plunger goes forward. Directlyvunder the partition t, and ng upon a board, S, is the lower plunger, H', which is provided with grooves, e', on its sides, which it into in the box similar to the plunger H, and is connected by a rod,f, to th second frame, D. This plunger as a presser, and forces the clay into the mould-frame after it has fallen from the upper plunger into the )tacle V. K represents the mould-frame, which is vertically-secured in the front end of the case A. This e has 'two or more brick-shaped openings, k, and is operated up and down in front of the ends of the gers H H. ,The lower en d of this mould-frame is provided with a pivoted benj, which said bar is pivoted e outer end of an arm, M, which is secured upon a shaft, and lies horizontally under the body of thc nine. The short end, N, df this arm is connected to the under part of the frame D', by means of a rod, O, at whenever this end N is forced down by the operation of the frame D,.the outer end, M, is carried ards, forcing the mould-frame past the plungers; and when the end N is carried upwards, the end M will rced down, bringing the mould-frame with it. i

[do not wish to be understood as confining myself to any particular number of cams, frames, or plungers, `o any particular number of brick-shapedopenings in frameK, as I may use any number of each, and operate ar frames and plungersV with their respective devices at each end of the frame. It will be seen that each e rollers F F have iheels a: x upon one end, and that the shaft B has a wheel, P, at its outer end, which ects the rollerwheels by a band or other device, by which the machine is operatcdi The operation of the machine is not material, :is any of the known devices may be applied therefor. By

Yarrangnred to act alternately, the clay is first carried into the revolution of shaft D the frames D D are caused to work laterally within their places, by the faces of cams C striking the inside of thc frames, and the bars E E striking against the flange b. These cams b the receptacle V by the first plunger, andas this. plu

.is drawn hack, the second plunger, H', forces the clay into the mould-frame K. The cam C being arrang( a diderent manner from the cams C, and the frame D likewise, it will be seen that as thc mould-frame is 1 and pressed intothe spaces k, the frame is then forced upwards, as heretofore described, and that the r end ofthe iirst plunger is then again thrown out so that it will bear against the formed brick in the space,

push it out upon the movable brick-board I, which lies upon a platform, I, at the end of the case. As

mould-frame is coming up, the loose cla;T is cut from it by a knife, l, which is secured crosswise within thc ofthe frame, between the two plu'ngers, thus smoothing the brick before it is forced out.

Haring `thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The vertical mould-frame K, constructed aud operating substantially as and for the purposes speci 2. The combination of the plunger H with the mould-frame K,;when constructed and operating subs -tially as set forth.

3. In combination with the cams C and frames D, the adjustable bars E E and flanges b, for assisting operation ef the plungers to carry the clay, substantially as set-forth..` l

4. The frame A, with rollers F F, secured upon shafts m m, above the throat G, frames D, opera plungers H H', receptacle V, knife l, platform J, with board I and frame K, all constructed. arranged, operating with their respectiveparts,.as and for the purposes herein fully described.

In testimony that I claim'the foregoing, I have hereunto set my hand, this 7th day of November, 186 EDWIN F. ANDREWS.A Witnesses:
